SELF-PLAYING ORGAN AND PNEUMATiCU-'A'CTION THEREFOR.

Application filed July 7.1902.l

SPECIFICATION forming part ofl Letters Patent No.i733,917, dated July14, 1903.

'Serial No.` 114,557. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH 1E. -PRANTIL a citizen ot' the United States,residing at'Chillicothe, in the county of Ross and State of rangement,and combination of the partsv v thereof.

Afurther object of the invention is to provide-improved means forseparating the wind-l chest into individual chest with back and frontcompartments, whereby the bass and treble chests are made separate anddistinct, and to provide such connections between'the compartments andthe pneumatics that anautomatic operation is effected.

Astill furtherobject of the invention is to ,provide novel means foradjusting the pipevalves whereby they admit air direct to the pipes, anautomatic pneumatic valve -lift having a dust-receptacle, and animproved tracker-board having downwardly-projectin g dust-receivingcells.

Various other special features in the actuating mechanism are employedto produce manyimproved results, which will be more particularly setforth in the specification and vpointed out in theclaims to follow.

In the accompanying drawings, forming part of this application, Figure 1is a crosssection without the casing with the pipes re' moved. Fig. 2 isa rear view of the several bellows and air connections to thewindchests. Fig. 3 is a section on the rim X X, Fig. 1, partly brokenaway. Fig. 4 is a lgngtudinal section of one of the air-chambers orindividual wind chests, partly broken away and showing only part ofthecell-valves. Fig. 5 is a'n' inverted planview of the windchests, partlybroken away. Fig. 6 is a detail vert' cal section of cneof thepneumatics.

Fig. 7 is a perspective view of one of the bellcrank levers with itsrods in position, partly broken away.- Fig. Sis a detail cross-sectionof one of the air-cells and its valves'. Fig. 9 is a perspective view ofone ofthe pneumatic dust-chambers. f

The same numeral references denote the same parts throughout the severalviews of the drawings.

The general appearance of my organ is substantially the same as those ofordinary make when viewed from ,the exterior, the casing andornamentation may be of any desired effect, and the pipes are oftheusual The music-paper rolls or cylinders are of the usual type andlocation, and the size, shape, and material of the several parts may besuch 'as are most suitable for producing 'the best results. The basswind-chest 1 and the treble wind-chest 2 are separated by a'nintervallvor space 3, in which. space are operated bellcrank levers 4,pivoted or fulcrumed at 5.

The bass and treble wind-chests 1 and 2, respectively, are, divided'bypartitions 1 and 2% into a series of air-chambers G, which are suppliedwith air from boxes 8, the latter being connected to the feed-bellows 9by airlues 10. Air is admitted to the chambers ,6 by independent valves11 of the boxes 8. Aircells 12 lead the air from the chambers 6 by wayof throats 13 in the partitions 1 and 2 to the music-pipes. The air tothese cells is controlled byvalves 15 and 16, having closing-springs 17and pendants 1S. Each set or line of the treble-valves 15 is connectedand operated together by tracker rods or wires 19, and the bass-valves16 are likewise connected-and operated together by similar trackers 20.These trackers 19 andj 2O extend through and are secured to the pendants18 and to the bell-crank levers by adjustingbuttons 21.

The pneumaticaction, of which there is of the latter, vand all beingalike only one will be herein described in detail. It consists of acasing having a back 22, a front 23, having air-ducts 2 4 and 24, andhollow air-stem 25,

construction and connection to the air-cells.

one for each air-chamber, located at the rear.

supporting and communicating with a bellows 36 and 37, working in saidseparate air-chambers `to open and close ,valveways 38 and 39, and abellows 40, connected to and operating the valve stem or rod 33. Securedwithin the pneumatic-casing and upon the bottom thereof is a block 41,having communication with the bellows 40 through a d ust receptacle orchamber 42, having a bottom opening 43 in communication with thedischarge-aperture 28, and an air-channel 44, reaching from the chamber42 to the air-duct 24. An air-pipe 43ck carries airtoa vacuum-bellows44a through an opening 45 in the back 22 of the casing from the cylinder32 to operate the bellows 40 and bellows 26. l

rlhe connection between the pneumatic-action and the valve-traekersconsists of bellcrank levers 4, pivoted or fulcrumed at 5, and throughone arm of which is adjustably attached trackers 19 and 2O by thebuttons 2l. To the other lever-arm is secured a connectingrod 48,attached to the bellows 26, so that the latter works one line of each ofthe set of valves 15 and 16.

The tracker-board 49 has air-ducts 50, to which are connected air-pipes51 in communication with the airducts 24 of the pneumatics,and thetracker-board is provided with dust-cells 52 below the rpoint ofconnection between said pipes and the board to collect dust orforeignmatter instead of having it enter the said pipes. Should-suchmattei' escape in to the pipes, the same will be collected in -thedust-chambcr 42, whence it is removedthrough the valves 29. Theperforated music-paper 53 is operated in the usual manner over thetracker-board by the rollers 54 and 55.

The operation is as follows: Supposing all the tracker-board ducts to beclosed by the non-perforated portion of the'paper and all` the bellows40 are closed, which closes valves 37 and opens valves 36 and bellows26,when

a perforation of the music-paper passes over a duct in the tracker-hoardthe air passes through a pipe 51, opening a bellows 40, which lifts thevalve-stern and opens valves 37, simultaneously closing valve Thisaction closes the bellows 26 and pulls the conneot- :ing-rods 48downwardly and operates the bell.- cranlr levers to work the trackersand open the 'valves 15 and 16. y

Having thus described my invention, what l claim as new, and desire tosecure by Letters Patent, is-

l. rlhe combination,y with a pneumatic for organs having a casing, of ablock secured in the casing in communications/ith the pneumaticandhaving a dustchamber, an airchannel extending from the chamberthrough the block, and a dust-discharge opening from ythe bottom of thechamber.

2. The combination, with the pneumatic having a casing, ay hollowstemprojecting from the casing, a pneumatic secured on the vsaid stem incommunication with the latter,

and a spring-valve hinged to the bottom of the casing, of a blocksecured within the cas- 'ing and having a dust-chamber dischargingthrough the valve, and an air-channel leading from said chamber throughthe casing, a

pneumatic secured on the block in comlnuv nication with thedust-chamber, and the rod having valves and attached to the latter pneulmatic.

3. The combination, with the wind-chests divided intoa series ofair-chambers and separated by an interval or space, bell-crank leversfulcrumed to the chest-casings and operated in said .,space, thepartitions of said chambers having a cell and a throat leadingtherefrom, spring-controlled valves hinged to the partitions, andtracker-rods connecting the valves with the .bell-crank levers, of thepneumatics having hollow stem projections bellows held by theprojections and in coming the bellows with the bell-crank levers.

In witness whereof I hereunto set my hand in the presence of twoWitnesses.
